That feature lets you physically set a hard limit on how far the pump strokes, which puts a cap on maximum flow output without having to rely solely on control signals. In practice, it gives you a mechanical backstop so the system can't accidentally demand more flow than your circuit is sized for. Useful in metal forming or injection molding setups where you want repeatable output limits without depending entirely on downstream controls to keep things in check.

Noise reduction is one of the called-out features on this PVM Series open circuit piston pump, with “50% less noise” listed along with outstanding performance and Pro-FX readiness.
